TYPOGRAPHICAL MACHINE.

. Application led November 16, 1921.

To all whom t may concern:

Re it known that I, Dsvm S. KENNEDY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State ot N ew York, have invented certain new and useful improvements in riypographical Machines, ot which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates more particularly to an arrangement such as covered hy my prior Letters Patent No. 1,347,638, wherein the storage magazine is provided with a permanent matrix locking device which may he instantly moved to active or inactive position at will, and which is arranged to control a magazine locking device in such manner as to permit and prevent the removal of the magazine as the matrices are locked and unlocked, respectively. The present invention is directed to certain improvements which are intended to simplify the construc tion and opera-tion ot the patented structure. rlhese improvements will hest he understood from the detailed description to follow.

Referring to the drawings:

Fig. 1 is a top plan view of the lower section of a linotype magazine equipped with my improvements, certain ot the parts heing broken away to show the interior construction and arrangement;

Fig. 2 is a section taken on the line 2,2 ot Fig. 1, and showing the matrix locking har in inactive position;

Fig. 3 is a similar' view but showing the matrix locking har in its active position;

Fig. 4; is a section taken on the line il-il ot Fig. 1;

Fig. 5 is vertical sect-ion, on an enlarged scale, taken through the lower end of the magazine Fig. 6 is a similar View, hut showing the matrix locking har projected into the magazine, and

Fig. 7 is a section taken on theline 7-7 of Fig. 2. y

The matrices X, stored in the channeled magazine A, are released therefrom one at a time by the escapements C, these latter heing supported in the har or trame C2 (Figs. 5 and 6). rllhe side plates of the magazine are formed on their inner faces with the op- S-pecication of Letters Patent,

posing grooves A1, wherein the projecting ears ot the matrices engage, the upper magazine plate having the detachable reentorced cover-section A2, and the lower' magazine plate having the openings A10 to receive the groovedpositions of the escapement supporting har C2, all in the usual way.

As in my prior patent before mentioned, the magazine is provided with a matrix locking har E seated and enclosed within a corresponding Vgroove A3 formed in the inner tace of the detachable section A2. Likewise, the har E is adapted to he moved to its active and inactive positions hy shitting it longitudinally in opposite directions,-that is to say, when shifted toward the lett, means are employed to project it sidewise into the magazine for locking the matrices therein, and when shifted toward the right, additional means are employed to withdraw it from the magazine for releasing the matrices. The first-mentioned means are substantially the same as disclosed vin they patented structure, consisting ot a plurality of huttons or protuherances A7 carried hy the magazine section A2 and adapted to cooperate with corresponding recesses or depressions F12 Y.tm-med in the upper side ot the har. ln the present instance, however, the depressions E2 are somewhat larger than those shown in the patent, presenting tlat bottom surfaces extending` parallel to the longitudinal axis oit the har, `tor vreasons which will later appear. 1n the patent, the second mentioned means are in the :term ot leali springs suitahly arranged tor the purpose stated; but, in the present arrangement, these springs are done away with and are replaced by a set et cam4 devices which act positively to withdraw the har `trom the magazine as it is shifted to the right. In the embodiment shown, such cam devices are made up, on the one hand, of a pair of headed pins El extended upwardly from the har E and secured thereto in any suitable manner, and, on the other hand, orn a pair of cam plates A4 detachahly secured to the magazine sect-ion A2 and termed with longitudinally arranged slots A5 wherein the pins El are slidahly arranged, it heing noted that the cam plates A* are also formed with tracks or ways A6 upon which the heads of the f bar in a raised condition and out of the path of the matrices (Figs. y5 and the protuberances A7 at this time being engaged v with the flat bottom surfaces of the depressions E2. lf now the bar 'be shifted to the left, its initial movement (which is a' longitudinal one only, as permitted by the flat bottom surfaces of thedepressions E2) disengages the heads of thel pins F1 from the upper surfaces of the cam plates A4' and brings them to the inclined positions of the traclrsyAF'. This initial movement of the bar simultaneously brings the curved walls of the' depressions F2 into engagementwith thev protuberances A7, which then act, by the continued movement of the bar, to displace it sidewise into the magazine (Fig. 6). The heads of the pins during such displacement slide along the tracks AG and finally run ont-o the straight parallel portions thereof, when further sidewise displacement of the bar is' prevented. The i'inal movement of the bar (which is also a longitudinal one only,A as permitted by the straight parallel portions of the tracks AG) disengages the depressions E2 entirely from the protuberances A7 and cause the latter to engage the straight upper sidev of the bar,'thereby maintaining the'bar irmly and securely in its loc-king positionfsee Fig. 3. Conversely, whenv the bar is shifted tothe right, its first movement (which is a longitudinal one only) brings the recesses E2 in position to receive the protuberances A7 and at the saine time carries .the heads of the pins El into engagement v with the inclined portions of the tracks AG;

its further movement then causes the heads of the pins El to climb up the inclined portions of ythe tracks A so as to lift the bar from the magazine, the prot-uberances A7 descending along the curved sloping walls of the ldepressions 'E2 until they become engaged with the flat bottom surfaces thereof; and4 itsiinal movement (which is also a longitudinal one only) then slides thel heads of the pins El onto the fiat upper surfaces of the cam plates A4,' in which condition of the parts, the bar is maintained irmly and securely in its uniocking position.

In these machines, before removing the magazines, it is desirable to push the matrices back up within the same to'disengage them from the escapements. 'In my prior patent, thisfresult was accomplished by moving the loclring'bar edgewise rearwardly of the magazine, but, in the present instance, such edgewise movement of the bar and consequently the means employed for producing it are dispensed with. In lieu thereof, and

shown in Figs. 5 to 7, the bar E is formed on its rear Aedge with a beveled surface E2 extending continuously along the bar from one end to the other. According to this construction, when the bar E is projected into the magazine in the manner previously described, the beveled surface E3 engages the upper ears of the l'owermost matrices and pushes themv rearwardly out of engagement ywith the escapements C (see Fig. 6). Of

course, when the bar is subsequently withdrawn from the magazine, the matrices are allowed to slide downwardly in the maga-v zine and again come under the control of the escapements (Fig. 5).

To insure the retention of the bar E in its different terminal positions, there is einployed a safety catch or dog (Figs. l to 4) slidably connected to the magazine ysection A2 by the pin-and-slot devices F1 and formed with 'a rectangular opening F2 through which the bar passes. A spring F3, pressing upwardly on a turned over part ofthe catch,

serves to engage the lower wall ofthe opening F2 in one or the other of two transverse notches E7 formed on the underside of the bar E. As will be apparent, the bar is free to be shifted in either direction by simply vpressing downwardly on the catch, which will then snap back into the appropriate notch E7 as the bar assumes one or the other of its terminal positions. lt may be noted v thatv the bar is formed with an upstanding handle ES which islocated immediately'adpicent the catch F, sothat the partsl may be easilyl and quickly manipulated.

Having thus described my invention, what l. A linotype magazine provided with a matrix locking bar shiftable longitudinally` in opposite directions, means for 'projecting the bar into the magazine as it is shiftedA in one direction and positively-,acting means for withdrawing the bar froml the magazine as it is shiftedin the opposite direction.

2. A linotype magazine provided with matrix locking bar shiftable longitudinally inopposite directions, and two sets of cam devices formed partly on the magazine'and partly on tlievlocking bar, one set acting as the bar is shifted in one direction to project it into the magazine, andthe other set acting as the bar is shifted inthe opposite direction to withdraw it from `the magazine. 5

3. A magazine as specied in claim 2, characterized by the fact that the 'cam devices therein 'recited aresofconstructed and arranged as to permit a slight independent longitudinal movement of the matrix locking barin each of its terminal positions,

so that the control of the bar may be transferred from one set of cam devices to the other and vice versa. f

4. The magazine A formed With the transverse groove A3, the longitudinally shiftable matrix locking bar E located in said groove and formed in its upper side With the recesses or depressions E2, the buttons or protuberances A7 arranged to cooperate with said recesses, the headed pins E1 attached to the locking bar, and the slotted cam plates A4 cooperating With said pins, substantially in the manner shown and described.

5. A linotype magazine provided with a matrix locking bar shiftable longitudinally in opposite directions and formed at one side with a pair of transverse notches, a locking plate formed With an opening through Which the bar extends, and a spring acting ou the plate and serving to engage a Wall of its opening in one or the other of the bar notches.

6. A linotype magazine provided with a matrix locking bar movable bodily into the magazine, the said bar being formed along its rear edge With a continuous beveled surface adapted to engage and push back the matrices Within the magazine.

7. Ay linotype magazine provided with a matrix locking bar shiftable longitudinally thereon, and means for projecting the bar sideWise into the magazine as it is shifted longitudinally, the said bar being formed along its rear edge with a beveled surface adapted to engage the matrices as the bar is projected into the magazine and push them rearwardly.

8. 'Ihe linotype magazine A formed with the transverse groove A3, the longitudinally shiftable matrix locking bar located in said groove and formed along its rear edge With the beveled surface E3, and means (such as the depressions E2 and the protuberances A7) for projecting the bar into the magazine as it is shifted longitudinally.

In testimony whereof, I have affixed my signature hereto.
